3f + 2g = 30 . . .(1)
f + 2g = 26 . . . .(2)
(1) - (2) => 2f = 4 => f = 4/2 = 2
From (2), 2 + 2g = 26 => 2g = 26 - 2 = 24 => g = 24/2 = 12
Therefore, f = 2 and g = 12
<h2>
The total number of ways = 1728 ways</h2>
Step-by-step explanation:
Given,
Math books = 4, History books = 3, Chemistry books = 3 and
Computer science books = 2
To find, the total number of ways = ?
∴ The total number of ways = 4! × 3! × 3! × 2!
= 24 × 6 × 6 × 2
= 24 × 72
= 1728 ways
∴ The total number of ways = 1728 ways

➷ Work out the original area:
(5 x 18) / 2 = 45cm^2
Increase/decrease the changed values:
18 x 0.7 = 12.6
5 x 1.2 = 6
New area:
(12.6 x 6) / 2 = 37.8cm^2
Calculate percentage change:
((45 - 37.8) / 45) x 100 = 16
16% decrease

Answer:
32
Step-by-step explanation:
Hello There!
The first thing we need to do is find the formula for area of a trapezoid
The formula is

where a= base 1
b = base 2
and h = height
we are given all of the dimensions so all we have to do is plug them in
sp

so the area of the figure is
32 units ²
It's going down by five but I'm sure on the last one..but to help add a zero like if it 0.5 it would be 0.50 that should help.
